WebPrinciples. Phase contrast angiography relies on dephasing the moving spins submitted to a bipolar gradient. For a bipolar gradient of a given intensity and time, the moving spins will dephase in proportion to their velocity. Similar to spatial encoding in the phase direction, the possible phase values range from – π to + π.
